Jacob Berzelius was one of the founders of modern chemistry. He was the first person to measure accurate atomic weights for the elements, which helped to confirm Dalton's Atomic Theory and was the basis of Mendeleev's periodic table. He discovered three chemical elements: cerium, thorium, and selenium, and devised the modern […] John Jacob Berzelius 1.

Bergström 1844. This important innovation finally translated chemistry into the language of atomic theory.

The most notable of Berzelius's contributions to chemistry was his development of a rational system of atomic symbols. Around 1810 Berzelius was working to confirm John Dalton's atomic theory as well as Proust's law showing that separate elements always combined in whole-number proportions. Berzelius, Jöns (1779-1848) Swedish chemist who was a disciple of Dalton. He developed the concepts of the ion and ionic compounds.

Se hela listan på biography.yourdictionary.com Berzelius developed the radical theory of chemical combination, which holds that reactions occur as stable groups of atoms called radicals are exchanged between molecules. He believed that salts are compounds of an acid and bases, and discovered that the anions in acids would be attracted to a positive electrode, whereas the cations in a base would be attracted to a negative electrode. 2018-05-29 · Jöns Jacob Berzelius.
